End Times prophecy is a topic that covers much more than just Communism. Whether the Communists takeover in Europe, or whether Europe absorbes the "former" Communists countries, the Bible clearly states that a revived Roman Empire (to include Russia), led by the anti-christ, will cause all who remain on earth to worship him, and will one day make war on Israel (but will really be waging war on God Himself). God intervenes in this war and utterly and totally destroys the forces of Satan. The EU increasingly fits the bill of the prophesied revival of the Roman Empire, not to mention the prophetic references to End Times references to Babylon. Could the EU be a fusion of the Endtimes depiction of the Revived Roman Empire and Mystical Babylon? Their symbols certainly seem to suggest so. If the people on the EU poster aren't being depicted as Communists, than nobody has ever been depicted as Communists in Communist art.

Ummm, ok, now in what part of make belief history was Russia part of the Roman Empire?

As for the EU, the same was said by protestants of the Holy Roman Empire and the Popes. Some even said this of Charlemaign's Empire. There have been many other candidates along that list too. If it's the EU then it's NATO and we're part of NATO, so I guess by your logic it's off to war we go against God.
